V Application filed January 21,1899. Serial No. 702,903. (No model.)

To @ZZ whom it may concern:

Be it known that I, FERDINAND PHILIPS, a subject of the Emperor of Germany, residing in the city and countyof Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Wheel Coustruction, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to the construction of wheels, and is particularly adapted for use in the construction of pulleys, the object of my invention being to provide a wheel at once simple, strong, and economical in construction.

My invention consists in part in improvements in the const-ructionof a sheet-metal rim for the wheel, in part in novel and advantageous features of construction in the spokes of the wheel, and in part in particular arrangements and connections of the spokes with the hub and rim. Y

The nature of my improvements will be bestunderstood as described in connection with the drawings, in which they are illustrated, and in which- Figure 1 is a side elevation of a wheel embodying my improvements, the rim being shown as in section on ,the line 1 1 of Fig. 2. Fig. 2 is a view of one-half of the wheel, taken on the section-line 2 2 of Fig. 1. Fig. 3 is a fragmentary View of a portion of the rim, showing a detail of construction. Fig. 4. is a perspectiveY View showing a detail of the spoke construction illustrated in Figs. 1 and 2. Fig. 5 is a plan View of the hub shown in Figs. 1 and 2. Fig. 6 is an end View of one of the hub-sections. Fig. 7 is a view illustrating a modified form of pulley embodying my invention. Fig. Sis an elevation showing another pulley of inodied form, but still embodying my invention,tl1e rim being shown as in section on the line 8 8 of Fig. -9. Fig. 9 is a sectional view taken on the line 9 9`of Fig. 8. Fig. 10 is a plan view of the hub as shown in the pulley illustrated in FigsjS and 9. Fig. 11 is an edge view of one section of the hub; Fig. 12, an end view'of the same hubsection; Fig. 13, a sectional View of the hubsection, taken as on the line 13 '13 of Fig. 10.

Fig. 14 is an elevation showing still another pulley embodying another modification of my invention. Fig. 15 is a section through the rim and connected parts of the spokes, taken on the line 15 15 of Fig. 14. Fig. 16 is an enlarged view o'f the joint by which the divisional rim-sections are secured together,I said view being taken as on the line 16 16 of Fig. 17. Fig. 17 is a View of the rim-joint, taken as on the line 17 17 of Fig. 16. Fig. 18 is a perspective view showing the manner in which the rim is cut and folded to form the abutting ends of the joint. Fig. 19 is a perspective view showing the manner in which the plies of the rim are folded and Secured together to form the abutting flanges of the joint. Fig. 2O is a section ou the line 20 20 of Fig. 19. Fig. 21 is a plan view showing the joint formed between two abutting rim-sections. Fig. 22 is a perspective View illustrating a modification in the formation of the abutting flanges for the joint. Fig. 23 is a section on the line 23 23 of Fig. 22. Fig. 24 is a view illustrating the joint made between two abutting rim-sections having flanges constructed as in Fig. 22. Figs. 25 and 26 Y illustrate two modifications in the make-up of the joint.

A in'all the figures indicates the sheet-metal rim, which may be properly called a twoply rim, as in all parts it consists of two layers or plies of the sheet metal folded the one upon the other. The outer layer of metal I have indicated by the letter d and the inner ply by the letter as, and preferably I turn the edges of the rim inward, forminginwardlyextending flanges, as indicated at a and a2. The outer ply of the metal is continuous, forming the face of the wheel or pulley without seam; but the inner plies as a3, formed by turning the sheet metal under the ply ct at each edge of the rim, are formed with inwardly-turned abutting anges, as indicated at d4 d4, forming an inwardly-extending twoply flange, to which the bars forming the spokes of the wheel are to lbe secured, and for certain constructions to be hereinafter described I prefer to form these inwardly-extending iianges with notches, Kas indicated at d5 a5. (Best shown in Fig. 3.) For both purposes and for the ordinary construction of breadth of face is required and where the rim is to be supported by what may be called two entirelydistinct sets of spokes, I construct the rim as is shown in Fig. 7, a second piece of sheet metal, (indicated at m6,) provided with inwardly-turned lianges a7, being set between the inwardly-turned iiangescti of the plies a3, and in this construction each of the spoke-connecting iianges is formed of the two abutting iianges (1,4 and a7. As in all sheet-metal rims, joints are necessarily to be provided for between abutted or connected ends of the rim, generallytwo such joints being used connecting two semicylindrical rimsections corresponding to two separable hubsections. Any convenient joint may be used for uniting the rim-sections; but I have invented and prefer to use the joints shown in the drawings and illustrated particularly in Figs. 16 to 26, inclusive. In forming this joint I cut the metal of the anges a4 a4 as indicated at x, Fig. 18, and the lianges ct a2 as indicated at y y, Fig. 1S, the plan of the cuts being approximately that at which the joint between rim ends or sections is to be made. For the strongest construction of joint I then bend the portion lying to the outside of these cuts upward, asindieated in Fig. 19, the upwardly-turned portion of the outer face or ply of the rim being indicated at h and the upwardly-turned portions of the inner plies as being indicated at b3. At the same time I spread the portions of the anges d4 lying in the turned-up portion, which, as a whole, I have indicated by the symbol B, apart, so that those portions indicated at b4 b4 will lap on each side of the flange formed by the abutted flanges a4, and I lap the turned-up portion of the flange a a2 on the inside of said ange, as is indicated at b b2, Fig. 19, and I secure the lapped portions of the flanges together, as by means of rivets. (Indicated at B and B2.) The joint between abutted ends or sections of the rim is then readily formed, as indicated in Fig. 2l,bolts or other anchoring devices BSBpassing through the abutted inwardly-turned end flanges of the rim-sections.

In many cases it will be unnecessary to make the end abutment flanges so heavy as they arein the above-described construction. Thus in Figs. 22 and 24 I have illustrated a construction in which the outer plies ct are turned up and in which the corresponding outer plies ct of the edge flanges of the wheel are not turned in, the end abutment lianges being formed by the upwardly-turned portion b3 of theinner plies a3 of the pulley-rim. This construction has a point of advantage in permitting of the formation of an abutted joint between the unturned edges of the outer plies a tt of the rim, as is best shown in Fig. 24. It is even quite sufficient to rely upon the lapped union between the fianges a4 and b4 to hold the end abutting flanges in place, the portion of the upwardly-turned end of the rim corresponding with the edge lianges being cut away, as indicated, for instance, by the dotted line at y, Fig. 18, and such a construction is illustrated in Fig. 25, while in Fig. 26 I have shown my abutment-joint applied to a rim made without the inwardly-turned edge flanges.

C C indicate the two halves of a divided pulley-hub having the general characteristics of such hubs as used with divided or sectional pulleys. As shown, they are made with laterally-extending perforated platforms, as indicated at C, supported on inwardly-tapering webs C2 and arranged to come opposite to each other, as shown, so that bolts D D, duc., can be used to fasten the two hub-sec-V tions together. In this feature my hub does not differ essentially from others in common use. The portion of the hub lying between the platform C is preferably formed with outwardly-projecting lugs, such as are indicated at C4 and C, or in Fig. 8 at c and c5, and these lugs or other parts of the hub corresponding to them in position are formed with perforations C6, running through them parallel to the axis of the hub and of a size and character adapted to admit of a pin or bolt, such as is indicated at H. As commonly used, the hubs are provided with liners such as are indicated at C7 C7. (See Figs. 8 and 9.)

I form the spokes of my wheel of relatively wide and thin plates or strips of sheet metal, such as are indicated at E E in the drawings, and preferably I stiifen and strengthen these plates by forming in them longitudinal corrugations, as indicated at e', (see Figs. 1 and 2,) and each spoke which is indicated by the letterE consists in my construction ot' two such wide and thin plates lying in planes substantially parallel to each other and transverse to the axis of the wheel, the plates being at their outer ends secured at a point on the rim of the wheel and diver-ging thence to two relatively widely separated points on the hub of the wheel, to which points they are secured, so that each spoke consists of what may be called a triangular truss, with its butt-end fastened t the hub and its apex to the rim ofthe wheel, and I greatly prefer and recommend that the securing otl the spokeplates to the hub shall in all cases be by means of pin connections, such as the pins II. The outer ends of the spoke-plates may also be secured to the rim or its flange a4 by pin connections, as indicated at G in Figs. 8, 9, and 14; but preferably I secure the outer ends of the spoke-plates not directly together but by rivets, as indicated at g', (see Fig. 1,) to a plate F, (best shown in Fig. 4,) the outer end of this plate being adapted to fit neatly into IOO IIO

izo

the notch or recess a5 (15in the rim-flange and the outer ends of the plates E', extending beyond theplate F, lapping and being secured to the ange a4 by rivets g g, as indicated in Figs. 1 and 2.

It is also an important feature of construction in my wheel that two sets of triangular spokes could be used, both secured to the same rim-liange, as a4, but each diverging from the plane of this rim-flange in opposite directions and being secu red on opposite ends of the hub, and in the drawings I have indi'- cated the spokes diverging in one direction by the letter E and those diverging in the opposite direction by the symbol EX. For the most part I have shown in the drawings the spokes of the set E and those of the set E as arranged opposite to each other, so as to form what might be called a single spoke of pyramidal outline. In Fig. 14, however, I have illustrated a permissible modification in which the spokes E and the spokes E have theirouter ends symmetrically spaced around the circumference of the rim, so as to present the appearance and to a certain extent the qualities of a wheel having double the number of spokes as compared with those of the other figures.

It will be obvious that the means for securing the triangular spokes to the hub-sections may be very considerably varied. Thus in Figs. l and 2 I provide each pulley-section with three spokes on each side, and the inner ends of the spoke-plates are secured,as shown, to four perforated lugs C4 and C5, four being secured on the pin H, passing through each of the lugs C4, and two of each of the pins H passing through the lugs C5. In Fig. 8, however, I have shown another construction in which but three perforated lugs are required on each hub-section, four spoke-bars being fastened to each pin H.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1.
